DETAILED DESCRIPTION
(34) The ensuing description provides embodiments only and is not intended to limit the scope, applicability, or configuration of the claims. Rather, the ensuing description will provide those skilled in the art with an enabling description for implementing the embodiments. It will be understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the appended claims.
(35) As an overview and one embodiment of the disclosure, a desktop is disclosed having a movable portion operable to accommodate a keyboard and moving to pitch away from a user when utilizing the keyboard. The purpose of tilting the keyboard up is to create a more neutral position for the arms and hands of the users in order to reduce or prevent this occurrence. This is particularly relevant when a user is utilizing a keyboard on an elevated work surface while standing or walking. (See,
(36) In order to maintain a proper ergonomic positioni.e., keeping the arms and hands in as neutral a position as possiblethe keyboard should be mounted at a much steeper angle than for desktop use. This could be anywhere from 20 to 60 degrees off the desktop plane. Using a keyboard when on a treadmill desk requires steeper angles than when sitting or standing due to the fact that the belt is constantly pulling the user backwards, causing them to press down harder on their palms in order to maintain hand position on the keyboard and typing accuracy. Lacking steeper angles, users eventually develop muscle strain in the neck and shoulders from maintaining hard downward pressure for extended periods. By working at a steeper angle this pressure is alleviated, resulting in the ability to type more accurately and faster typing speeds and treadmill belt speeds, plus reduced muscle strain.
(37) The first component of the invention is a single solid mounting frame. For example, see
(38) The frame has arms that extend backward under the table. These arms provide several benefits. While attaching the frame, before it is tightened on, it keeps the front part of the frame, including the keyboard and peripheral surfaces, from swinging down and sliding forward off the desk. Instead, the arms that extend backward keep the frame in an upright position. Once the frame is attached and tightened to the table, these arms provide a secure counter lever that extends back from the edge to the center of the desk it is attached to. This causes any downward forces on the keyboard surface or peripheral surfaces on the front of the frame to be transferred to upward forces on the back end of the lever arm directly to the table top close to the center of gravity of the table. This is because the front lip/plate that attaches to the table top acts like the center of the lever. This result is a very strong and rigid mounting of the frame. This direct transfer does not introduce additional wiggle or wobble since it is one solid part, rather than multiple parts that could have additional room to wiggle or potentially fail to hold together under significant forces, such as if someone walking on a treadmill while typing stumbles and puts the majority of their body weight on the frame.
(39) An additional benefit of the arms that extend backward under the table and the lip/plate that attaches in the front is that together they allow the frame to be mounted on a table top when the front underside edge is not entirely flat. Some desktops have frame members (or other obstructions) that are close to the front edge of the table top. These obstructions prevent other keyboard mounting systems from being used in these scenarios. Most adjustable-height desks have crossbars that block this installation of conventional keyboard trays. This frame mechanism requires a relatively shallow freeboard between the user edge of the desk and the crossbar allowing it to be mounted universally to almost any kind of deskmany more than any other keyboard tray design.
(40) Another component of this system is the keyboard surface and how it mounts to the frame. The frame has a single rod or axle that the keyboard surface attaches to via mounting clamps. The mounting clamps provide the ability to mount the surface at any latitudinal angle. This complete adjustability allows any ergonomic angle to be achieved. This angle can be adjusted correctly for an individual, whether a person is sitting, standing, or walking at their desk. Another benefit of the surface and frame connection is that the axle, which is part of the single solid frame, extends entirely under the keyboard surface. All forces from someone pushing on the keyboard surface are conveyed directly downward on to the frame. Other systems have less secure and less strong connection points on the side of the keyboard surface. The other systems do not allow for the complete adjustability of the angle. Most other systems are limited in potential tilt angle of the keyboard platform by obstruction of the arm that connects them to the desk. And the mechanism for keeping the angle in place in the other systems does not have as much surface area for friction to hold the angle in place. Another embodiment of this would be instead of an axle or rod that would allow continuous adjustments, there may be a different a bar (rectangular or other polygon or grooved shape) combined with a corresponding clamp, which would allow for continuous or a finite number of adjustable positions.
(41) An additional aspect of the clamps that attach the keyboard surface to the axle are the number of clamps. In the
(42) Another component that is attached to the keyboard surface are pegs (or in other instances an adjustable fence or plate) that holds the keyboard in place so that it does not slide off the back end of the keyboard surface when the keyboard is at a significantly steep angle for holding the keyboard in the standing or walking position. In addition, these pegs are adjustable so that they can be positioned as far forward or backward as needed to hold the keyboard forward on the surface at the desired distance from the front edge. As a result, the front of the keyboard can be positions to hold an optional standard ergonomic wrist pad if desired.
(43) The keyboard system also has a rear fence along the back edge of the keyboard surface to further prevent anything from sliding off the back edge of the surface. Additional items, like a pencil and pen can be kept on the surface without sliding off the back edge. This fence has the additional feature that it has one or more slots to hold the cable (commonly a USB or PS2 cable) that is used to connect the keyboard with a computer. This keeps the cable neatly tucked away and holds it in place so it does not get tangled up with other components.
(44) Another aspect of the system is an extension to the mounting frame and the addition of peripheral surfaces on the left and right sides of the keyboard surface. The frame would have similar rod, axle, or bar that extends to the sides of the frame (see illustrations). The key aspect of this is that this rod is at an angle to the keyboard axle. In an embodiment, the angle is, for example, 45 degrees. This angle may be optimized in other instances for the correct ergonomic positions. By these rods turning, for example, 45 degrees towards the user, the side surfaces are able to effectively be closer to the body of the person using the system. This reduces the distance that a person has to reach to the side a peripheral on the side surface such as a mouse or trackball. This allows a better ergonomic position to be achieved, by allowing the user to use their pointing device (e.g., mouse, trackball, trackpad, or other device) without any pronation, supination, flexion, or extension of the wrists.
(45) Additionally, the side surface mounts to the axle with a mechanism similar to that described above for the keyboard platform, allowing any angle of incline of the surface to be achieved. Another important part of this invention is that this adjustment is completely independent of the adjustment of the angle of the keyboard surface. As a result, these angles can be optimized for the desired ergonomics independently of the keyboard angle and of each other. Adjusting one does not require the user to re-adjust the other. Existing keyboard positioning systems do not have independent adjustments that do not affect each other. When an adjustment is made to the keyboard angle, the existing systems adjust the peripheral surface angle as well since the two are tied together.
(46) Similar to the keyboard surface, the peripheral surface has a rear fence on the back edges of the surface to keep items from rolling off the back edge. It also has slots in the back fence to allow for cable management to keep cables neat and from getting tangled up.
(47) The peripheral surface also has movable pegs (or fences or plates) for keeping a mouse or trackball at the appropriate position on the surface. In the case of a mouse (or similar other pointing devices), which a person is moving relative to the surface, when a person lets go of the mouse, they do not want it to slide all the way to the back edge of the surface (or off the back of there was no back fence either). If it did, then they would have to reach further away to resume using the device. So the pegs are able to be positioned on the surface to allow the mouse to slide only a short distance away from the primary mousing area. In the case of a trackball, the user can position the pegs so the trackball is as close to the front edge of the peripheral surface as a person would want it, as to minimize how far a person would have to reach forward, thus allowing for a better ergonomic adjustment.
(48) An additional variation of this invention is that the keyboard surface and axle mounting bar are mounted inside the outer dimensions of a desktop surface in an area cut out from the desktop. In addition to all the benefits of the keyboard mounting system previously described, this brings the overall center of gravity closer to the center of the desk, resulting in less movement of the desktop when forces are exerted on the keyboard positioning system. Also, the shape of the cutout has angled edges (the omega shape), which allow for the person's body to easily get closer to the table and reach a mouse or trackball in those locations on the table.
(49) Additionally, in those locations, there would be an optional individually positionable platform at preset or adjustable angles that would be made up of the peripheral surface with adjustable pegs and rear fences. These platforms could be independent from the desktop or integrated with the desktop.
